To aZZ wlwm t may comem:

Be it known that I, FRANK a citizen Vof the United. States, residing at Shreveport, in the parish of Gaddo, State of Louisiana, have invented certain newand useful Improvements'in Doors, of which the following is a` speciication.

This invention relates 1n general to doors, and more particularly tol an automatically operable ycounterbalanced door especially adapted for use in garages.

An object of the.-1nvention is to rovide a door of vthis character which may e conveniently and easily operated to effect either opening or closing thereof and .which isso constructed, mountedy and -counterbalanced as-to automatically vopen or close .under the control of the person entering or leaving the garage.

A furtherl object ofthe invention istoV provide a door of this character having these advantages'and capacities and which is'also of simple and durable construction, reliable Y in 'operation and easy and comparativelyinexpensive to manufacture. y

vOther objects andf-A advantages reside in certain novel features vof the construction, arrangement `and combination of parts which willbe hereinafter .more fully 'gdescribed andy particularly pointed out in the appended claims, reference being had to the accompanying drawings forming apart of this specification, and in which.: y 4

y, Figure 1- is a view in longitudinal lvertical section taken approximatel'yon the line 1 1 of Figure 2 and showing a garage and door constructed in accordance with the present invention, and f .y

Figure 2 is a view in transverse vertical section takenV approximately on the line p 2-2 of Figure 1. y

horizontal cross pieces 16 and uprights 12'v secured to the cross pieces 16. The panel or body of the door is secured to the cross pieces 16. As vshown to advantage in Figure 2, the two upper cross pieces 16 are formed with extensions 18 at each side of B. Drcxnsorr,V

vand hasone end connected, as at 36, rtothe 4or pivotallymounted, as at .21,7190` standards 22.` rIt is proposed torigidlykconnect one kend of each-.lever tothe door and for this purposey the forward `end of .each lever-I is notched'and, the extensions 18of the cen trallydlsposed cross piece-16 are vfitted in the v4`notches at the forward ends ofr the `lecal bracemember 2,4;l extends between and is secured tothe extensions 18k at leach side of the door and y th-is brace member 24 together with an inolined brace member at each side of lthe door provides a trussed mounting framey at each sideof the door. It is tobe understood, of course, that the inclined brace rnembers25extend between and aresecured to the levers20 and the lvertical brace mem bers 24 soi that thertruss is constituted by4 thebrace members `24 and25 and thecom# prehendedportion of the` lever20.

Counter-weights 30 are fixed vto, theufree ends ofthe levers 20 and are provided for the purpose of counterbalancing the door 15. In Aorder to limit the movements -of the `door toppenfand closed position, stops `31 and -32 are provided.V `The sto s 31 and 32 may lconsistof pins fixed to .t e stationav structure v of the. arznge'` and covered wit sleeves of cushioning.v material.

-A-lexble operating relement. 35 such as a cord, cable, chain orthe like, isprovided upper cross piece 16,'ofthe doorl fram'in The voperating `element 35kextends rearwar y and upwardly from the door and passes through af: 1 ide 37 which may consist ofan lordinarys eave or pulley mounted on a transversely extending'bar 38. Beyond the Y guide 37 the operating element 35 extends forwardly of the garage and out 'through'an opening 39 in the front wall thereof to an'ypoint where it is desired to exercise control of the door.

' In order to providev for proper cimnterbalancing of the door in wet weather, auxiliary counter-weights 40 may be employed.

In operation, with the door in closed posi- 1 tion, asshown in Fi re 1, the panel vor body portion of the oor is` disposed in a plane parallel to the front face of the wall of the garage since the upper end of the door is accommodatedin the recess 14|. .The 4110 .65 vers and also secured to the levers. Aver'tilower end-ofthe door rests ongthe floor 11 of the garage` While the stops 31 co-a'ct.

with the floor in holding the door 15 against the further swinging ina clockwise direction from the position shown in Fig. v1. If

it is desired to open thedoor only a slight pull need be exerted on the flexible operaty ing a slightpull on 'the operat-ingl cord 35.

as will be understood from an inspection ofthe dotted lineA position of the cord shown in Figure 1. The door -partakes of all its movement in-a smooth and easy fashion so thatno shocks or strains are set up in any of the elements of the structure. The cable 35' may be extended to anyl suitable' point and provides' 'for a distant control ofthe door. Y I claim: 'y a f 1. In a garage door, a' pair of vertical standards, 'the members of said pair of standards being located at the opposite sides of the door, alever fulcrumedon'each standard, a-'r'igid doory structure fixedly secured to the forward ends of the levers, the levers and the door structure being arranged at right angles, the levers being horizontally disposed in the closed position of the door and being vertically disposed in y thel open position of the door, and counter-Weights secured to the rear ends of the levers.

2. In a garage door, a pair of vertical standardgthe members of said pairy of standards being located at the opposite sides of the door, aleverfulcrumed on each standard, a rigid door structure fiXedly secured to the forwardends of the levers, the levers and the door structure' being arranged at right angles, thev levers beingk horizontally disposed in the closed position of the door and being vertically disposed in the open position of thedoor, counterw'eightsv secured to the` rear ends of the levers, and stops co- `operable'with the counterweights for limitingthe movement of the doorto open and closed position.

3. In combination with a building structure having a Wall provided With a door opening7 the portion of the Wall immediat-eliv above the opening being recessed, a rigid oor structure co-operable with the door opening, a pair of vertical standards, inembers of said pair of standards being located at the opposite sides of the door, a lever fulcrulned on each standard, the forward ends of the levers being iiXedly secured to the door structure, the levers being horizontally disposed in the closed position of thedoor, the door in its closed position having its lower end resting onzthe floor of the building structure and having its upper end received in the recess of the front Wall, the levers being vertically disposed in the. open position of the door, and a counter- Weight mounted on each lever at the end thereof opposite the door.l

4. In combination Witha building structure having a wall provided vwith a door opening, the portion of the Wall immediateabove the opening being recessed, a rigid l olbor structure co-operable with the door opening, a pairof vertical standards, members of said pair of standards being located at the opposite-sides of the door, a lever fulcrumed on each standard, the forward ends of the levers being fixedly secured to the door structure, the levers being horizontally disposedv in the closed positionvr of the door, the door inn/its lclosed position having itsv lower end resting on the floor of the building structure and having its upper end received in the recessl of the front wall, vthe levers being vertically disposed in the open position of the door, a /counterweight mounted on each lever at the end thereof opposite 'the door, a guidepulley mounted on the building structure'rearwardly of the door, and an operating cord having one end conn'ected to the innerl sideof the door, said operating cord being trained around the pulley and extended forwardly of the door to a point of convenient control eXteriorly of the building.
